Abstract (en)
According to one embodiment, a light detector (100) includes an element (10), and a structure body (20). The element (10) includes a first semiconductor region (1), a second semiconductor region (2), and a third semiconductor region (3). The second semiconductor region (2) is provided on the first semiconductor region (1). The third semiconductor region (3) is provided on the second semiconductor region (2). The structure body (20) is provided around the element (10) in a first plane perpendicular to a first direction. The structure body (20) includes first and second insulating portions (21, 22) and a metal-including portion (25). The metal-including portion (25) is provided above the first insulating portion (21). A position in the first direction of at least a portion of the metal-including portion (25) is same as a position in the first direction of the third semiconductor region (3). The second insulating portion (22) is positioned between the metal-including portion (25) and the element (10) in the first plane. A thickness of the first insulating portion (21) is greater than a thickness of the second insulating portion (22) in the first plane.
